I had to use an F motor. The A didn't have enough power to get mine in the air with the A engine and 2 cell battery. The F pack with a 2 cell was great scale flying. Then still enough power to fight any wind.

Tried to use magnets with removable wing... not a great idea if you fly anything but scale. However, it just goes to show how great of a design this is. Fall from 50 ft with no significant damage after the wing came off in flight. Just a few wrinkles. Taped the wing on without the magnets (also not a good idea). Another unexpected crash from 50 feet. 5 minutes later, tried to fly with rubber-banded wings but was too windy to get it trimmed. (I did not lose the wing, though.) I will definitely make a fleet of these. Great flyer and can handle much more wind than the sport cub.
This is such a smooth flyer! It's definitely one of the best flying planes I've ever flown!
